IMPROVEMENT IN SUSPENSION-LAMPS.

Specification formingpart of Letters Patent No. 150,770, dated May 12,1874 application filed January 5, 187.4.

a vertical section representing a lamp suspended according to myinvention. Fig. 2 is a lamp where they suspension-plate is differ.

ently applied.

In the former case the plate and the shade are made to balance the lamp.In the latter case a weight is employed, and the lamp and the shaderetain the same in relative position. A is the lamp; B,'the shade; O,the sus pension-plate. This plate may be made in any form to serve as areflector to-throw the rays of light downward. The plate is fastened tothe shade by means of screws D,

which pass through the vertical flange E, and enter one of thecorrugations Fin the shade, as seen in the drawing. H are thesuspension-chains, one end of each of which is attached to the plate (J.The other ends are carried up and passed over pulleys I in thesuspensionbracket J, and then down through holes in the plate, and areattached to the rods K K,

which arefa-st to the lamp. By this arrangement the plate 0 and theshade B are made to balance the lamp. L is the chimney, which isattached to the cone of the burner by any of the different modes, sothat it can be readily removed for filling lighting, or extinguishingthe lamp. Then this is done the lamp is drawn down so that the shadewill not interfere with the chimney when the latter is turned down. N Nare rings in the chains, which, when the lamp is raised, stop it in theright posit-ion, as they will not pass through the holes in the plate Gwith the chain. v In Fig. 2, 0 represents the weight which balances thelamp andthe shade. The two latter retain their relative position, andare raised and lowered together, the chimney being provided with guidesP, which pass through the plate 0, and is lifted up, as represented, forfilling, lighting, and extinguishing the lamp. The lamp is alsoconnected with the plate 0 by means of rods, as seenin the drawing.Ornamental pieces, of any design, may be attached to the plate 0, so asto hang over the top or below the shade. The plate 0 may be made doubleor single, as may be desired. This plate 0 is essentially a combination-plate, as it serves as a reflector, as well as for attaching thesuspensionchains, and serving as a guide and as a base forornamentation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The plate 0, suspended from lamp-chains andattached to and within a shade, B, substantially as described, to serveboth as a reflector and connection between the lamp and shade, allowingeither to be raised or lowered.

2. The comblnation of the screws D, plate flange E, and corrugatedshade-neck, as and for the purpose specified.
